SPECIFICATION forming part of Letters Patent No. 777,671, dated December20, 1904.

Application filed March 26,1964. Serial No. 200,110.

To {all} whom t may concern:

Be it known that I, ERNEST T. FRY, a citizen of the United States,residing at Mount Jackn son, in the county of Shenandoah and State ofVirginia, have invented certain new and useful Improvements inVVindow-Shade Adjust ers, of which the following is a specilication.

This invention relates generally to windowshades, and particularly tomeans for vertically adjusting' the shade-rollers and with them theshades themselves- It is well known that it is a great conven ience inthe use of window-shades to be able to readily and quickly adjust themand their supporting-rollers to bring the rollers nearer to or fartherfrom the top of the windows.

The object of the present invention is to provide improved means wherebya window-shade roller may be thus adjusted in order that light may beadmitted above the shade or air permitted to flow freely into or out ofthe room to regulate the temperature or change the air therein.

With this object in view the invention consists in the improvedconstruction, arrange ment, and combination of the parts of such anadjusting device, all as fully described hereinafter and afterwardspecifically pointed out in the appended claims.

In order that others may be enabled to construct and use my invention, Ishall now proceed to fully describe the construction and operation ofits several parts in connection with the accompanying drawings, in whichFigure l represents in front elevation part 0f a window-frame with myinvention in place thereon, the shade and roller beingI shown raised infull lines and lowered in dotted lines. Fig. 2 represents in sideelevation part of the frame with the shade and rollerin their lowerpositions. Fig. 3 represents in detail 1n side elevation one of thebracket-arms, part thereof being broken away. Fig. 4L represents indetail the hook for retaining the shade and roller raised. Fig.represents in detail the hook for retaining' the shade and rollerlowered. Fig. 6 represents in front elevation the window-:frame with thetop broken out and the lower part broken away, showing therolleroperating means -vertically adjustable on side rods. Fig. 7represents in side elevation one of the side rods with a slidablerockshaft bearing thereon, the rod being partly broken out. Fig. 8represents in detail part of the operating-rod and its angular end.

Like reference characters niark the same parts wherever they occur inthe several ligures of the drawings.

Referring specifically to the drawings, 1 indicates the top, and 2 and 3the sides, of thc window-frame, which may be of any suitable form orsize.

At 4f 4 are secured to the sides of the frame I suitable bearings, whichmay be ordinary screw-eyes or staples. to support a rock-shaft 5, whichcarries at each end an arm, as at 6 and 7, capable of being turned tothe upper position, as shown in Figs. 1 and 6, or the lower position, asshown in Fig. 2 and in dotted lines in Fig. l. rIhese arms formrollersupporting brackets, the arm 6 being provided with the usual roundhole to receive the rigidly-attached pintle 8 and the arm 7 with aT-shaped recess or notch 9 to receive the angular spring-impelled pintlel0 of any ordinary spring shade-roller 11. The arms 6 and 7 may be madeintegral parts of the rockshaft 5; but I prefer to make the arm 7separate therefrom and secured rigidly thereon in any suitablemanner-such. for instance, as by means of a set-screw IQ-the shaftentering a hole 13 in said bracket-arm 5.

By mounting the shade-roller in the bearings in the usual manner theshade and roller may be adjusted near to the top l of the frame byturningI the bracket-arms 6 and 7 into ver tical positions along thesides 2 3 of the frame, so that the shade will cover the extreme upperportion of the window, or they may be adjusted to their lower positionby turning the bracket downward, bringing the roller to a position aboutthe distance of two lengths of the bracket-arms below the top of thewindow, so that light and air may be admitted through the upper part ofthe window. It being necessary to hold the shade-roller 11 in either itsupper' or lower position the bracketarm 7 is provided with a verticalslot 14, eX- tending from the hole 13, in which the rockshaft issecured, nearly to the notch 9, which forms the bearing for the angularpintle 10 of the roller, as best shown in Fig. 3.

At 15 is indicated an elastic wire or metal rod provided with an eye 16or other suitable handle at its lower end and with an arm 17, bent at aright angle to its upper end andannularly grooved near its outer end,Jforming a shoulder 18, a head 19, and a reduced stem 2O between them.

At 21 I show an upturned hook and at 22 a straight hook, both secured inthe frame, the former at the height of the bracket-arm 7 when raised toits highest position and the latter in position to engage the wire orrod 15 when in its lowest position. The reduced stem 20 is of a suitablethickness to slide freely in the vertical slot 14, and the parts areassembled by slipping said stem into said slot from thehole 13 in arm 7,which receives the rock-shaft, securing the rock-shaft in its bearingsand in said opening, thereby preventing the escape of the stem from theslot and mounting the shade-roller 11 in its bearings in thebracket-arms 6 and 7. Normally the roller would assume its lowerposition, as

'in Fig. 2, in which the reduced stem 2O ot' arm 17 will hang in the endof the slot nearest the shade-roller bearing and the rod 15 lie againstthe side of the frame, being held slightly oi the frame by the eye orhandle 16 at its lower end, when it may be secured against easydisplacement by springing it under the straight hook 22, whereby theshade and roller will be held against flapping or swinging outward underthe influence of wind entering the window when open.

To adjust to and maintain the roller in its upper position, it is onlynecessary to withdraw the rod 15 from under the hook 22, push it upward,thus turning the rock-shaft and carrying the roller upward until the arm17 can be engaged over the upturned hook 21.

In order to permit of the adjustment of the height of the shade-rollerbeyond the limit of about twice the length of the bracket-arms 6 and 7,I provide heavy wires or rods 23 in staple form, having angular ends 24,formed as pins, by which I secure the rods in place on the frame, uponwhich rods I mount slidable blocks 25, provided with openings 26 to formbearings for the rock-shaft 5, which blocks may be vertically adjustedand secured in any positions on said rod 22 by any suitable meansas, forinstance, set-screws 26. By the vertical adjustment of the rock-shaft(mounted in these slidable bearing-blocks) the limit of adjustment ofthe shade-roller may be increased at will to the extent of the length ofthe rods.

Vhile I have specifically described the construction and arrangementofthe various parts composing my invention, I do not limit myself tosuch specific constructions and arrangements, as many slight changestherein or variations therefrom might be made Without departing from thespirit and scope of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is#
